In situations such as this, the body, the underbody, chassis components, wheels or tires could be damaged without the damage being visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, may not absorb the loads that arise as intended. If the underbody paneling is damaged, flam mable materials such as leaves, grass or twigs can collect between the underbody and the underbody paneling. These materials may ignite if they come into contact with hot parts on the exhaust system.

# Have the vehicle checked and repaired immediately at a qualified specialist workshop.

or # If driving safety is impaired while con

tinuing your journey, pull over and stop the vehicle immediately in accordance with the traffic conditions, and contact a qualified specialist workshop.

In addition, your vehicle provides comfort and entertainment functions, which are also made possible by electronic control units. Electronic control units contain data memories which can temporarily or permanently store technical information about the vehicle's operat ing state, component loads, maintenance requirements and technical events or malfunc tions.

In general, this information documents the state of a component part, a module, a system or the surroundings such as: R Operating status of system components (e.g.

fill levels, battery status, tire pressure) R Status messages concerning the vehicle or

its individual components (e.g. number of wheel revolutions/speed, longitudinal accel eration, lateral acceleration, display of fas tened seat belts) R Malfunctions or faults in important system

components (e.g. lights, brakes) R Information on events leading to vehicle

damage R System reactions in special driving situations

(e.g. airbag deployment, intervention of sta bility control systems) R Ambient conditions (e.g. temperature, rain

sensor)

In addition to providing the actual control unit function, this data assists the manufacturer in detecting and rectifying malfunctions and opti mizing vehicle functions. The majority of this

data is temporary and is only processed in the vehicle itself. Only a small portion of the data is stored in the event or fault memory. When your vehicle is serviced, technical data from the vehicle can be read out by service net work employees (e.g. workshops, manufactur ers) or third parties (e.g. breakdown services). Services include, for example, repair services, maintenance processes, warranty claims and quality assurance measures. The read out is per formed via the legally prescribed port for the diagnostics connection in the vehicle. The respective service network locations or third parties collect, process and use the data. They document technical statuses of the vehicle, assist in finding faults and improving quality and are transmitted to the manufacturer, if neces sary. Furthermore, the manufacturer is subject to product liability. For this, the manufacturer requires technical data from vehicles. Fault memories in the vehicle can be reset by a service outlet as part of repair or maintenance work.

General notes 29

Depending on the selected equipment, you can import data into vehicle convenience and info tainment functions yourself. This includes, for example: R Multimedia data such as music, films or pho

tos for playback in an integrated multimedia system R Address book data for use in connection with

an integrated hands-free system or an inte grated navigation system R Entered navigation destinations R Data about the use of Internet services

This data can be saved locally in the vehicle or it is located on a device which you have connected to the vehicle (e.g. a smartphone, USB flash drive or MP3 player). If this data is stored in the vehicle, you can delete it at any time. This data is sent to third parties only at your request, par ticularly when you use online services in accord ance with the settings that you have selected. You can store or change convenience settings/ individualization in the vehicle at any time.

Depending on the equipment, this includes, for example: R Settings for the seat and steering wheel posi

tions R Suspension and climate control settings R Customizations such as interior lighting

If your vehicle is accordingly equipped, you can connect your smartphone or another mobile end device to the vehicle. You can control this by means of the control elements integrated in the vehicle. Images and audio from the smartphone can be output via the multimedia system. Cer tain information is simultaneously transferred to your smartphone. Depending on the type of integration, this can include: R General vehicle data R Position data

This allows you to use selected apps on your smartphone, such as navigation or music play back. There is no further interaction between the smartphone and the vehicle; in particular, vehi cle data is not directly accessible. Which type of

further data processing occurs is determined by the provider of the specific app used. Which set tings you can make, if any, depends on the spe cific app and the operating system of your smartphone.

Online services

Wireless network connection If your vehicle has a wireless network connec tion, it enables data to be exchanged between your vehicle and additional systems. The wire less network connection is enabled via the vehi cle's transmission and reception unit or via con nected mobile end devices (e.g. smartphones). Online functions can be used via the wireless network connection. This includes online serv ices and applications/apps provided by the man ufacturer or other providers.

Manufacturer's services Regarding online services of the manufacturer, the individual functions are described by the manufacturer in a suitable place (e.g. Operator's Manual, website of the manufacturer) along with the relevant data protection information. Per

30 General notes

sonal data may be used for the provision of online services. Data is exchanged via a secure connection, e.g. the manufacturer's designated IT systems. Personal data is collected, pro cessed and used via the provision of services exclusively on the basis of legal permissions or with prior consent. The services and functions (sometimes subject to a fee) can usually be activated or deactivated. In some cases, this also applies to the entire vehicle's data connection. This excludes, in par ticular, legally prescribed functions and services.

Third party services If it is possible to use online services from other providers, these services are the responsibility of the provider in question and subject to that provider's data protection conditions and terms of use. The manufacturer has no influence on the content exchanged. For this reason, please ask the service provider for information about the type, extent and pur pose of the collection and use of personal data when services are provided by third parties.

Multimedia system/Mercedes me connect

If the vehicle is equipped with the multimedia system or Mercedes me connect, additional data about the vehicle's operation, the use of the vehicle in certain situations, and the location of the vehicle may be compiled by the multimedia system or Mercedes me connect. For additional information please refer to the chapter "Multimedia system" and/or the Mercedes me connect Terms and Conditions.

Event data recorders

USA only: This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like sit uations, such as an airbag deployment or hitting a road obstacle, data that will assist in under standing how a vehicle's systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less.

The EDR in this vehicle is designed to record such data as: R How various systems in your vehicle were

operating R Whether or not the driver and front

passenger seat belts were buckled/fastened R How far (if at all) the driver was depressing

the accelerator and/or brake pedal and R How fast the vehicle was traveling

This data can help provide a better understand ing of the circumstances in which accidents and injuries occur. NOTE: EDR data is recorded by your vehicle only if a non-trivial crash situation occurs; no data is recorded by the EDR under normal driving conditions and no personal data (e.g. name, gender, age and accident location) is recorded. However, other parties, such as law enforcement, could combine EDR data with the type of personally identifying data routinely acquired during a crash investigation. To read data recorded by an EDR, special equip ment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties that have the special

General notes 31

equipment, such as law enforcement, can read the information by accessing the vehicle or the EDR. EDR data may be used in civil and criminal mat ters as a tool in accident reconstruction, acci dent claims and vehicle safety. Since the Crash Data Retrieval (CDR) tool that is used to extract data from the EDR is commercially available, Mercedes-Benz USA, LLC ("MBUSA") expressly disclaims any and all liability arising from the extraction of this information by unauthorized Mercedes-Benz personnel. MBUSA will not share EDR data with others with out the consent of the vehicle owner or, if the vehicle is leased, without the consent of the les see. Exceptions to this representation include responses to subpoenas by law enforcement; by federal, state or local government; in connection with or arising out of litigation involving MBUSA or its subsidiaries and affiliates; or, as required by law. Warning: The EDR is a component of the Restraint System Module. Tampering with, alter ing, modifying or removing the EDR component

may result in a malfunction of the Restraint Sys tem Module and other systems. State laws or regulations regarding EDRs that conflict with federal regulation are pre-empted. This means that in the event of such conflict, the federal regulation governs. As of December 2016, 17 states have enacted laws relating to EDRs.

32 General notes

Restraint system Protection provided by the restraint system

The restraint system includes the following com ponents: R Seat belt system R Airbags R Child restraint system R Child seat securing systems

The restraint system can help prevent the vehi cle occupants from coming into contact with parts of the vehicle interior in the event of an accident. In the event of an accident, the restraint system can also reduce the forces to which the vehicle occupants are subjected. A seat belt can only provide the best level of pro tection if it is worn correctly. Depending on the detected accident situation, Emergency Tension ing Devices and/or airbags supplement the pro tection offered by a correctly worn seat belt. Emergency Tensioning Devices and/or airbags are not deployed in every accident.

In order for the restraint system to provide the intended level of protection, each vehicle occu pant must observe the following information: R Fasten seat belts correctly. R Sit in an almost upright seat position with

their back against the seat backrest. R Sit with their feet resting on the floor, if pos

sible. R Always secure persons under 5 ft (1.50 m)

tall in an additional restraint system suitable for Mercedes-Benz vehicles.

However, no system available today can com pletely eliminate injuries and fatalities in every accident situation. In particular, the seat belt and airbag generally do not protect against objects penetrating the vehicle from the outside. It is also not possible to completely rule out the risk of injury caused by the airbag deploying.

Reduced restraint system protection

& WARNING Risk of injury or death due to modifications to the restraint system

Vehicle occupants may no longer be protec ted as intended if alterations are made to the restraint system. # Never alter the parts of the restraint

system. # Never tamper with the wiring or any

electronic component parts or their software.

If it is necessary to modify the vehicle to accom modate a person with disabilities, contact an authorized Mercedes-Benz Center for details. USA only: for details, contact our Customer Assistance Center on 1-800-FOR-MERCedes (18003676372).

Restraint system functionality

When the ignition is switched on, a self-test is performed, during which the 6 restraint sys

Occupant safety 33

tem warning lamp lights up. It goes out no later than a few seconds after the vehicle is started. The components of the restraint system are then functional.

Malfunctioning restraint system

A malfunction has occurred in the restraint sys tem if: R The 6 restraint system warning lamp

does not light up when the ignition is switched on R The 6 restraint system warning lamp

lights up continuously or repeatedly during a journey

& WARNING Risk of injury due to malfunc tions in the restraint system

Components in the restraint system may be activated unintentionally or not deploy as planned in an accident. # Have the restraint system checked and

repaired immediately at a qualified spe cialist workshop.

Function of the restraint system in an acci dent

How the restraint system works is determined by the severity of the impact detected and the type of accident anticipated: R Frontal impact R Rear impact R Side impact R Rollover

The activation thresholds for the components of the restraint system are determined based on the evaluation of the sensor values measured at various points in the vehicle. This process is pre- emptive in nature. The triggering/deployment of the components of the restraint system must take place in good time at the start of the colli sion. Factors which can only be seen and measured after a collision has occurred do not play a deci sive role in the deployment of an airbag. Nor do they provide an indication of airbag deployment. The vehicle may be deformed significantly with out an airbag being deployed. This is the case if

only parts which are relatively easily deformed are affected and the rate of vehicle deceleration is not high. Conversely, an airbag may be deployed even though the vehicle suffers only minor deformation. If very rigid vehicle parts such as longitudinal members are hit, this may result in sufficiently high levels of vehicle decel eration. Depending on the detected deployment situa tion, the components of the restraint system can be activated or deployed independently of each other: R Emergency Tensioning Device: frontal

impact, rear impact, side impact, rollover R Driver's airbag, front passenger airbag: fron

tal impact R Knee airbag: frontal impact R Side airbag: side impact R Head airbag: side impact, rollover, frontal

impact

The front passenger airbag can only be deployed in an accident if the PASSENGER AIR BAG OFF indicator lamp is off. If the front passenger seat

34 Occupant safety

is occupied, make sure, both before and during the journey, that the status of the front passenger airbag is correct (/ page 44).

& WARNING Risk of burns from hot air bag components

The air bag parts are hot after an air bag has been deployed. # Do not touch the air bag parts. # Have a deployed air bag replaced at a

qualified specialist workshop as soon as possible.

Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop after an accident. Take this into account, partic ularly if an Emergency Tensioning Device is trig gered or an airbag deployed. If the Emergency Tensioning Devices are trig gered or an airbag is deployed, you will hear a bang, and a small amount of powder may also be released: R The bang will not generally affect your hear

ing.

R In general, the powder released is not haz ardous to health but may cause short-term breathing difficulties to persons suffering from asthma or other pulmonary conditions. Provided it is safe to do so, leave the vehicle immediately or open the window in order to prevent breathing difficulties.

Airbags and pyrotechnic Emergency Tensioning Devices contain perchlorate material, which may require special handling or environmental pro tection measures. National guidelines regarding waste disposal must be observed. In California, see https://dtsc.ca.gov/. Using the search function, you will find information on perchlo rate, for example.

Seat belts Protection provided by the seat belt

Always fasten your seat belt correctly before starting a journey. A seat belt can only provide the best level of protection if it is worn correctly.

& WARNING Risk of injury or death due to incorrectly fastened seat belt

If the seat belt is not worn correctly, it can not perform its intended protective function. In addition, an incorrectly fastened seat belt can also cause injuries, for example, in the event of an accident or when braking or changing direction suddenly. # Always ensure that all vehicle occu

pants have their seat belts fastened correctly and are sitting properly.

Always observe the instructions about the cor rect driver's seat position and adjusting the seat (/ page 83). In order for the correctly worn seat belt to pro vide the intended level of protection, each vehi cle occupant must observe the following infor mation: R The seat belt must not be twisted and must

fit tightly and snugly across the body.

Occupant safety 35

R The seat belt must be routed across the cen ter of the shoulder and as low down across the hips as possible. R The shoulder section of the seat belt should

not touch your neck nor be routed under your arm or behind your back. R Avoid wearing bulky clothing, e.g. a winter

coat. R Push the lap belt down as far as possible

across your hips and pull tight with the shoul der section of the belt. Never route the lap belt across your abdomen. Pregnant women must also take particular care with this. R Never route the seat belt across sharp, poin

ted, abrasive or fragile objects. R Only one person should use each seat belt at

any one time. Never allow babies and chil dren to travel sitting on the lap of another vehicle occupant. R Never secure objects with a seat belt if the

seat belt is also being used by one of the vehicle's occupants. Always observe the instructions for loading the vehicle when

securing objects, luggage or loads (/ page 97). Also ensure that no objects, e.g. a cushion, are ever placed between a person and the seat.

The seat belts on the following seats are equip ped with a special seat belt retractor: R Front passenger seat R Rear seats

Activate or deactivate the special seatbelt retractor (/ page 53). If children are traveling in the vehicle, be sure to observe the instructions and safety notes on "Children in the vehicle" (/ page 50).

Limitations of the protection provided by the seat belt

& WARNING Risk of injury or death due to an incorrect seat position

The seat belt does not offer the intended level of protection if you have not moved the seat backrest to an almost vertical position. You could slip beneath the seat belt and injure yourself. # Adjust the seat properly before com

mencing your journey. # Always ensure that the seat backrest is

in an almost vertical position and that the shoulder belt is routed across the center of your shoulder.

& WARNING Risk of injury or death due to an extended seat belt extender while the vehicle is in motion

If the seat belt does not sit correctly on the body, it cannot perform its intended protec tive function.

sible.

The front passenger airbag may otherwise be disabled by mistake, for example, in the follow ing situations: R The front passenger transfers their weight by

supporting themselves on a vehicle armrest. R The front passenger sits in such a way that

their weight is raised from the sitting sur face.

& WARNING Risk of injury or death due to a disabled front passenger airbag

The front passenger airbag is disabled when the PASSENGER AIR BAG OFF indicator lamp is lit.

A person in the front passenger seat could then, for example, come into contact with the vehicle interior, especially if the person is sitting too close to the cockpit. If the front passenger seat is occupied, always ensure that: R The classification of the person in the

front passenger seat is correct and the front passenger airbag is enabled or disa bled in accordance with the person in the front passenger seat. R The front passenger seat has been moved

as far back as possible. R The person is seated correctly.

# Both before and during the journey, ensure that the status of the front passenger airbag is correct.

If the front passenger seat is occupied, the clas sification of the person or child restraint system on the front passenger seat takes place after the front passenger airbag shutoff self-test. The PASSENGER AIR BAG indicator lamps display the status of the front passenger airbag.

Always observe the notes on the function of the PASSENGER AIR BAG indicator lamps (/ page 44).

Function of the PASSENGER AIR BAG indica tor lamps

44 Occupant safety

Self-test of automatic front passenger airbag shutoff When the ignition is switched on, a self-test is performed during which the two PASSENGER AIR BAG ON and OFF indicator lamps light up simultaneously. The status of the front passenger airbag is dis played after the self-test: R PASSENGER AIR BAG ON lights up for

60 seconds, subsequently both indicator lamps are off (PASSENGER AIR BAG ON and OFF): the front passenger airbag is able to deploy in the event of an accident. R PASSENGER AIR BAG OFF lights up continu

ously: the front passenger airbag is disabled. It will then not be deployed in the event of an accident.

If the PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front passenger airbag. The PASSENGER AIR BAG OFF indicator lamp may be lit continuously or be off. If the PASSENGER AIR BAG OFF indicator lamp and the 6 restraint system warning lamp

PRE-SAFE system PRE-SAFE (anticipatory occupant protec tion)

PRE-SAFE is able to detect certain critical driv ing situations and implement pre-emptive meas ures to protect the vehicle occupants.

PRE-SAFE can implement the following meas ures independently of each other: R Tightening the seat belts on the driver's seat

and front passenger seat. R Closing the side windows. R Vehicles with memory function: Move the

front passenger seat to a more favorable seat position. R Vehicles with multicontour seat: Increase

the air pressure in the seat side bolsters of the seat backrest. R PRE-SAFE Sound: provided that the multi

media system is switched on, generates a brief noise signal to stimulate the innate pro tective mechanism of a person's hearing.

* NOTE Damage caused by objects in the footwell or behind the seat

The automatic adjustment of the seat posi tion may result in damage to the seat and/or the object. # Stow objects in a suitable place.

Reversing the PRE-SAFE system measures

If an accident did not occur, the pre-emptive measures that were taken are reversed. You will need to perform certain settings your self. # If the seat belt pre-tensioning is not reduced,

move the seat backrest back slightly. The locking mechanism releases.

Function of PRE-SAFE PLUS (anticipatory occupant protection plus)

PRE-SAFE PLUS can detect certain impacts, particularly an imminent rear impact, and take pre-emptive measures to protect the vehicle

occupants. These measures cannot necessarily prevent an imminent impact.

PRE-SAFE PLUS can implement the following measures independently of each other: R Tightening the seat belts on the driver's seat

and front passenger seat. R Increasing brake pressure when the vehicle

is stationary. This brake application is can celed automatically when the vehicle pulls away.

If an accident did not occur, the pre-emptive measures that were taken are reversed.

System limits The system will not initiate any action in the fol lowing situations: R when backing up

The system will not initiate any braking applica tion in the following situations: R whilst driving

Safely transporting children in the vehicle Always observe when children are traveling in the vehicle

% Also strictly observe the safety notes for the specific situation. In this way you can recog nize potential risks and avoid dangers if chil dren are traveling in the vehicle (/ page 50).

Be diligent Bear in mind that negligence when securing the child in the child restraint system may have seri ous consequences. Always be diligent in secur ing a child carefully before every journey. To improve protection for children younger than twelve years old or under 5 ft (1.50 m) in height, Mercedes-Benz recommends you observe the following information: R Always secure the child in a child restraint

system suitable for this Mercedes-Benz vehi cle.

R The child restraint system must be appropri ate to the age, weight and size of the child. R The vehicle seat must be suitable for instal

ling a child restraint system.

Accident statistics show that children secured on the rear seats are generally safer than chil dren secured on the front seats. For this reason, Mercedes-Benz strongly advises that you install a child restraint system on a rear seat.

The generic term child restraint system The generic term child restraint system is used in this Operator's Manual. A child restraint sys tem is, for example: R a baby car seat R a rearward-facing child seat R a forward-facing child seat R a child booster seat with a backrest and seat

belt guide Mercedes-Benz recommends using a child booster seat with a backrest.

The child restraint system must be appropriate to the age, weight and size of the child.

Observe laws and legal requirements Always observe the legal requirements when using a child restraint system in the vehicle.

Observe standards for child restraint sys tems All child restraint systems must meet the follow ing standards: R U.S. Federal Motor Vehicle Safety Standards

213 and 225 R Canadian Motor Vehicle Safety Standards

213 and 210.2

Confirmation that the child restraint system complies with the standards can be found on an instruction label on the child restraint system. This confirmation can also be found in the instal lation instructions that are included with the child restraint system.

Occupant safety 49

Detecting risks, avoiding danger

Securing systems for child restraint systems in the vehicle Only use the following securing systems for child restraint systems: R the LATCH-type (ISOFIX) mounting brackets R the vehicle's seat belt system

Installing a LATCH-type (ISOFIX) child restraint system is preferred. Simply attaching to the securing rings on the vehicle can reduce the risk of installing the child restraint system incorrectly. When securing a child with the integrated seat belt of the LATCH-type (ISOFIX) child restraint system, always comply with the permissible gross weight for the child and child restraint sys tem (/ page 54). A booster seat may be necessary to achieve proper seat belt positioning for children over 40 lbs (18 kg) in weight or until they reach a height where a three-point seat belt can be fas tened properly without a booster seat.

Mercedes-Benz recommends a suitable child booster seat with a backrest and seat belt guide.

Advantage of a rearward-facing child restraint system It is preferable to transport a baby or a small child in a suitable rearward-facing child restraint system. In this case, the child sits in the oppo site direction to the direction of travel and faces backwards. Babies and small children have comparatively weak neck muscles in relation to the size and weight of their head. The risk of injury to the cer vical spine during an accident can be reduced in a rearward-facing child restraint system.

Always secure a child restraint system cor rectly

& WARNING Risk of injury or death due to incorrect installation of the child restraint system

The child can then not be protected or restrained as intended.

# Be sure to comply with the manufactur er's installation instructions for the child restraint system and its correct use.

# Make sure that the entire base of the child restraint system always rests on the sitting surface of the seat.

# Never place objects (e.g. cushions) under or behind the child restraint sys tem.

# Use child restraint systems only with the original cover designed for them.

# Always replace damaged covers with genuine covers.

& WARNING Risk of injury or death due to unsecured child restraint systems in the vehicle

If the child restraint system is incorrectly installed or not secured, it can come loose. The child restraint system could be flung around and hit vehicle occupants.

speeds. R drive the vehicle in drive programA

or;. R shift to the next highest gear at the very lat

est when the needle reaches the last third before the red area in the tachometer. R do not shift down a gear manually in order to

brake. R avoid overstraining the vehicle, e.g. driving at

full throttle.

128 Driving and parking

R do not depress the accelerator pedal past the pressure point (kickdown). R only increase the engine speed gradually and

accelerate the vehicle to full speed after 1,000 miles (1,500 km).

This also applies when the engine or parts of the drivetrain have been replaced. Please also observe the following breaking-in notes: R in certain driving and driving safety systems,

the sensors adjust automatically while a cer tain distance is being driven after the vehicle has been delivered or after repairs. Full sys tem effectiveness is not reached until the end of this teach-in process. R brakepads, brake discs and tires that are

either new or have been replaced only ach ieve optimum braking effect and grip after several hundred miles of driving. Compen sate for the reduced braking effect by apply ing greater force to the brake pedal.

Notes on optimized acceleration

If all necessary requirements and activation con ditions are fulfilled, the best possible accelera tion can be achieved from a standstill. Do not use the optimized acceleration on public roads. Individual wheels could spin and you could lose control of the vehicle. There is an increased risk of skidding and/or accident. Be sure to observe the safety notes and informa tion on ESP (/ page 152).

Pulling away with optimized acceleration

& WARNING Risk of skidding and having an accident from wheels spinning

When you use optimized acceleration, indi vidual wheels could spin and you could lose control of the vehicle.

If ESP is deactivated, there is a risk of skid ding and accident. # Make sure that no persons or obstacles

are in the close vicinity of your vehicle.

Requirements: R The vehicle has been broken in

(/ page 128). R The vehicle and tires are in good condition. R You are on a high-grip roadway. R The engine and transmission are at normal

operating temperature.

* NOTE Increased wear due to optimized acceleration

When pulling away with optimized accelera tion, all components of the drivetrain are subjected to a very high load. This can lead to increased component wear. # Do not always pull away with optimized

acceleration.

# Engage theh drive position (/ page 138). # Move the steering wheel to the straight-

ahead position. # Select the sportiest available drive program B orC(/ page 135).

& DANGER Risk of death caused by exhaust gases

Combustion engines emit poisonous exhaust gases such as carbon monoxide. Inhaling these exhaust gases is hazardous to health and leads to poisoning. # Never leave the engine or, if present,

the auxiliary heating running in an enclosed space without sufficient venti lation.

& WARNING Risk of skidding and of an accident due to shifting down on slippery road surfaces

If you shift down on slippery road surfaces to increase the engine braking effect, the drive wheels may lose traction. # Do not shift down on slippery road sur

faces to increase the engine braking effect.

& DANGER Risk of fatal injury due to poi sonous exhaust gases

If the tailpipe is blocked or sufficient ventila tion is not possible, poisonous exhaust gases such as carbon monoxide may enter the vehi cle. This is the case when the vehicle becomes stuck in snow, for example. # Keep the tailpipe and the area around

the vehicle free from snow when the engine or the stationary heater are run ning.

# Open a window on the side of the vehi cle facing away from the wind to ensure an adequate supply of fresh air.

& WARNING Risk of accident and injury due to being under the influence of alco hol and drugs while driving

Driving when under the influence of alcohol and/or drugs is an extremely dangerous combination. Even small quantities of alcohol or drugs may affect your reflexes, perception and judgment.

The probability of a serious or even fatal acci dent greatly increases if you drive when under the influence of alcohol or drugs. # Do not drink alcohol or take drugs while

driving, and do not allow anyone to drive who has been drinking alcohol or taking drugs.

Driving and driving safety systems Driving systems and your responsibility

Your vehicle is equipped with driving systems which assist you in driving, parking and maneu vering the vehicle. The driving systems are only aids. They are not a substitute for your attention to the surroundings and do not relieve you of your responsibility pertaining to road traffic law. The driver is always responsible for maintaining a safe distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Pay attention to the traffic conditions at all times and intervene when necessary. Be aware of the limitations regarding the safe use of these systems. Driving systems can neither reduce the risk of accident if you fail to adapt your driving style nor override the laws of physics. They cannot always take into account road, weather or traffic condi tions.

Information on vehicle sensors and cameras

1 Cameras in the outside mirrors 2 Multifunction camera 3 Front camera 4 Ultrasonic sensors 5 Rear view camera

% Depending on the vehicle's equipment, the radar sensors are integrated behind the bumpers and/or behind the radiator grill.

Some driving and driving safety systems use cameras as well as radar or ultrasonic sensors to monitor the area in front of, behind or next to the vehicle. Keep the areas around the sensors and cameras free of dirt, ice or slush (/ page 340). The cam eras and sensors must not be covered, for exam ple by bicycle racks, overhanging loads, stickers, foil or foils to protect against stone chipping. Additional license plate brackets can impair the function of the ultrasonic sensors, in particular. In the event of damage or a severe impact in the area of the sensors, have the function of the sensors checked at a qualified specialist work shop. Have damage or stone chipping in the area of the cameras repaired at a qualified specialist workshop. If the sensors or cameras are dam aged, some driving systems and driving safety systems may no longer function properly.

Function of BAS

The Brake Assist System (BAS) supports your emergency braking situation with additional brake force. If you depress the brake pedal quickly, BAS is activated: R BAS automatically boosts the brake pres

sure. R BAS can shorten the braking distance. R ABS prevents the wheels from locking.

The brakes will function as usual once you release the brake pedal. BAS is deactivated.

Function of ESP (Electronic Stability Pro gram)

& WARNING Risk of skidding if ESP is deactivated

If you deactivate ESP, ESP cannot carry out vehicle stabilization.

# ESP should only be deactivated in the following situations.

Mercedes-AMG vehicles: observe the notes in the Supplement. You could otherwise fail to rec ognize dangers.

ESP can monitor and improve driving stability and traction in the following situations, within physical limits: R When pulling away on a wet or slippery road. R When braking.

If the vehicle deviates from the direction desired by the driver, ESP can stabilize the vehicle by intervening in the following ways: R One or more wheels are braked. R The engine output is adapted according to

the situation.

When ESP is deactivated, the warning lamp lights up continuously: R Driving stability will no longer be improved. R The drive wheels could spin.

R ETS/4ETS traction control is still active.

% When ESP is deactivated, you are still assis ted by ESP when braking.

When the warning lamp flashes, one or several wheels has reached its grip limit: R Adapt your driving style to suit the current

road and weather conditions. R Do not deactivate ESP. R Only depress the accelerator pedal as far as

is necessary when pulling away.

Deactivate ESP in the following situations to improve traction: R When using snow chains. R In deep snow. R On sand or gravel.

% Spinning the wheels results in a cutting action, which enhances traction.

If the ESP warning lamp lights up continu ously, ESP is not available due to a malfunction.

152 Driving and parking

Observe the following information: R Indicator and warning lamps (/ page 454) R Display messages (/ page 407)

ETS/4ETS (Electronic Traction System) ETS/4ETS traction control is part of ESP and makes it possible to pull away and accelerate on a slippery road. ETS/4ETS can improve the vehicle's traction by intervening in the following ways: R The drive wheels are braked individually if

they spin. R More drive torque is transferred to the wheel

or wheels with traction.

Influence of drive programs on ESP

The drive programs enable ESP to adapt to dif ferent weather and road conditions as well as the driver's preferred driving style. You can select the drive programs using the DYNAMIC SELECT switch (/ page 135).

ESP modes Depending on the selected drive program, the appropriate ESP mode will be activated auto

matically. You can select the drive programs using the DYNAMIC SELECT switch (/ page 135).

ESP is deactivated if the ESP OFF warn ing lamp lights up continuously in the instrument cluster. Observe the information on warning lamps and display messages which may be shown in the instrument cluster.

Function of ESP Crosswind Assist

ESP Crosswind Assist detects sudden gusts of side wind and helps the driver to keep the vehi cle in the lane: R ESP Crosswind Assist is active at vehicle

speeds between approx. 50 mph (80 km/h)

Driving and parking 153

and 125 mph (200 km/h) when driving straight ahead or cornering slightly. R The vehicle is stabilized by means of individ

ual brake application on one side.

Function of EBD

Electronic Breakforce Distribution (EBD) is char acterized by the following: R Monitoring and regulating the brake pressure

on the rear wheels. R Improved driving stability when braking,

especially on bends.

Function of STEER CONTROL

STEER CONTROL helps you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilization. This steering recommendation is given particu larly in the following situations: R Both right wheels or both left wheels are on

a wet or slippery road surface when you brake.

R The vehicle starts to skid.

System limits STEER CONTROL may be impaired or may not function in the following situations: R ESP is deactivated. R ESP is malfunctioning. R The steering is malfunctioning.

If ESP is malfunctioning, you will be assisted further by the electric power steering.

Function of Active Brake Assist

Active Brake Assist consists of the following functions: R Distance warning function R Autonomous braking function R Situation-dependent braking assistance R Vehicles with Driving Assistance Pack

age: Evasive Steering Assist and cornering function

Active Brake Assist can help you to minimize the risk of a collision with vehicles, cyclists or pedestrians, or reduce the effects of such a colli sion. If Active Brake Assist has detected a risk of colli sion, a warning tone sounds and theL dis tance warning lamp lights up in the instrument cluster. If you do not react to the warning, autonomous braking can be initiated in critical situations. In especially critical situations, Active Brake Assist can initiate autonomous braking directly. In this case, the warning lamp and warning tone occur simultaneously with the braking applica tion. If you apply the brake yourself in a critical situa tion or apply the brake during autonomous brak ing, situation-dependent braking assistance occurs. The brake pressure increases up to max imum full-stop braking if necessary. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog nize dangers (/ page 150).

154 Driving and parking

If autonomous braking or situation-dependent braking assistance has occurred, display1 appears in the multifunction display and then automatically goes out after a short time.

& WARNING Risk of an accident caused by limited detection performance of Active Brake Assist

Active Brake Assist cannot always clearly identify objects and complex traffic situa tions. # Always pay careful attention to the traf

fic situation; do not rely on Active Brake Assist alone. Active Brake Assist is only

an aid. The driver is responsible for maintaining a sufficiently safe distance to the vehicle in front, vehicle speed and for braking in good time.

# Be prepared to brake or swerve if nec essary.

Also observe the system limits of Active Brake Assist.

The individual subfunctions are available in various speed ranges: The distance warning function can issue a warn ing in the following situations: R From approximately 4 mph (7 km/h), if your

vehicle is critically close to a vehicle, cyclist or pedestrian, you will hear an intermittent warning tone and theL distance warning lamp lights up in the instrument cluster.

Function of Active Speed Limit Assist

If speed limit change between 12 mph (20 km/h) and 80 mph (130 km/h) is detected and the automatic adoption of speed limits is active, it will be automatically adopted as the stored speed (/ page 192). The driven speed is adjusted when the vehicle is level with the traffic sign at the latest. In the case of signs indicating entry into an urban area, the speed is adapted according to the speed permitted within the urban area. The speed limit display in the Instrument Display is always upda ted when the vehicle is level with the traffic sign. If there is no speed restriction on an unlimited stretch of road (e.g. on a freeway), the recom mended speed is automatically adopted as the stored speed. The system uses the speed stored on an unlimited stretch of road as the recom mended speed. If you do not alter the stored speed on an unlimited stretch of road, the rec ommended speed is 80 mph (130 km/h). If Active Distance Assist DISTRONIC has been put into passive mode by pressing the accelera

tor pedal, only speed limits which are higher than the set speed are adopted. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog nize dangers (/ page 150).

System limits The system limits of Traffic Sign Assist apply to the detection of traffic signs (/ page 191). Speed limits below 12 mph (20 km/h) are not automatically adopted by the system as the stored speed. Temporary speed restrictions (e.g. for a certain time or due to weather conditions) cannot be properly detected by the system. The maximum permissible speed applying to a vehi cle with a trailer is not detected by the system. Adjust the speed in these situations.

& WARNING Risk of accident due to Active Speed Limit Assist adapting the vehicle's speed

The speed adopted by Active Speed Limit Assist may be too high or incorrect in some individual cases, such as:

R at speed limits below 12 mph (20 km/h) R in wet conditions or in fog R when towing a trailer

# Ensure that the driven speed complies with traffic regulations.

# Adjust the driving speed to suit current traffic and weather conditions.

Function of route-based speed adaptation

When Active Distance Assist DISTRONIC is acti vated, the vehicle speed will be adapted accord ingly to the route events ahead. Depending on the drive program selected, the vehicle negoti ates a route event ahead in a fuel-saving, com fortable or dynamic manner. When the route event has been passed, the vehicle accelerates again to the stored speed. The set distance to the vehicle in front, vehicles detected ahead and speed restrictions ahead are taken into account. Route-based speed adaptation can be config ured in the multimedia system (/ page 166).

Driving and parking 165

The following route events are taken into account: R Curves R T-intersections, roundabouts and toll stations R Turns and exits

% When the toll station is reached, Active Dis tance Assist DISTRONIC adopts the speed as the stored speed.

Also, the speed is reduced if the turn signal indi cator to change lanes is switched on and one of the following situations is detected: R Turning off at intersections R Driving on slowing-down lanes R Driving on lanes adjacent to slowing-down

lanes

The driver is responsible for choosing the right speed and observing other road users. This applies in particular to intersections, round abouts and traffic lights, as route-based speed adaptation does not brake the vehicle to a stand still.

When route guidance is active, the first speed adjustment is carried out automatically. If the turn signal indicator is switched on, the selected route is confirmed and further speed adjustment is activated. Speed adaptation is canceled in the following cases: R If the turn signal indicator is switched off

before the route event. R If the driver depresses the accelerator or

brake pedal during the process.

System limits Route-based speed adaptation does not take right of way regulations into account. The driver is responsible for complying with road traffic regulations and driving at a suitable speed. In difficult conditions, the speed selection made by the system may not always be suitable: R unclear roads R road narrowing R wet road surfaces, snow or ice

In these situations the driver must intervene accordingly.

& WARNING Risk of accident in spite of route-based speed adaptation

Route-based speed adaptation can malfunc tion or be temporarily unavailable in the fol lowing situations: R If the driver does not follow the calcula

ted route R If map data is not up-to-date or available R In the event of roadworks R In bad weather or road conditions R If the accelerator pedal is depressed R In the event of electronically displayed

speed limitations

Active Steering Assist

Function of Active Steering Assist Active Steering Assist is only available up to a speed of 130 mph (210 km/h). The system helps you to stay in the center of the lane by means of moderate steering interventions. Depending on the speed driven, Active Steering Assist uses the vehicles ahead and lane markings as a refer ence. % Depending on the country, in the lower

speed range Active Steering Assist can use the surrounding traffic as a reference. If nec essary, Active Steering Assist can then also provide assistance when driving outside the center of the lane, for example to form a res cue lane.

If the detection of lane markings and vehicles ahead is impaired, Active Steering Assist switches to passive mode. The system provides no support in this case.

Status display of Active Steering Assist in the multifunction display R (gray): activated and passive R (green): activated and active R (red): system limits detected R (white, red hands): "hands on the steer

ing wheel" prompt

% During the transition from active to passive status, the symbol is shown as enlarged and flashing. Once the system is passive, the symbol is shown as gray in the multifunction display.

% Depending on the selected vehicle settings, Active Steering Assist may be unavailable.

Steering and touch detection The driver is required to keep their hands on the steering wheel at all times and be able to inter vene at any time to correct the course of the vehicle and keep it in lane. The driver must

expect a change from active to passive mode or vice versa at any time.

If the system detects that the driver has not steered the vehicle for a considerable period of time or has removed their hands from the steer ing wheel, display1 appears. If the driver still does not steer the vehicle, a warning tone sounds in addition to the visual warning mes sage. If the driver does not react to this warning for a considerable period, an emergency stop is initi ated (/ page 170).

Driving and parking 167

The warning is not issued or is stopped when the driver gives confirmation to the system: R The driver steers the vehicle. R The driver presses a steering wheel button or

operates Touch Control.

If Active Steering Assist detects that a system limit has been reached, a visual warning is issued and a warning tone sounds. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog nize dangers (/ page 150).

System limits Active Steering Assist has a limited steering tor que for lateral guidance. In some cases, the steering intervention is not sufficient to keep the vehicle in the lane or to drive through exits. The system may be impaired or may not function in the following instances: R There is poor visibility, e.g. due to snow, rain,

fog, heavy spray, greatly varying ambient light or strong shadows on the road. R There is glare, e.g. from oncoming traffic,

direct sunlight or reflections.

R Insufficient road illumination. R The windshield is dirty, fogged up, damaged

or covered in the vicinity of the camera, e.g. by a sticker. R No, or several, unclear lane markings are

present for one lane, or the markings change quickly, for example, in a construction area or intersections. R The lane markings are worn away, dark or

covered up, e.g. by dirt or snow. R If the distance to the vehicle in front is too

short and thus the lane markings cannot be detected. R The road is narrow and winding. R There are obstacles on the lane or projecting

out into the lane, such as object markers.

The system does not provide assistance in the following conditions: R On tight curves and when turning. R When crossing intersections. R At roundabouts or toll stations. R When the tire pressure is too low.

& WARNING Risk of accident if Active Steering Assist unexpectedly stops func tioning

If the system limits of Active Steering Assist are reached there is no guarantee that the system will remain active or will keep the vehicle in lane. # Always keep your hands on the steering

wheel and observe the traffic carefully. # Always steer the vehicle paying atten

tion to traffic conditions.

& WARNING Risk of accident if Active Steering Assist unexpectedly intervenes

The detection of lane markings and objects may malfunction and cause unexpected steering interventions. # Steer according to traffic conditions.

Function of Active Lane Change Assist

Active Lane Change Assist supports the driver when changing lanes by applying steering torque if the driver operates a turn signal indicator. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog nize dangers (/ page 150). Assistance when changing lanes is provided if all the following conditions are met: R You are driving on a freeway or road with

multiple lanes in the direction of travel. R The neighboring lane is separated by a bro

ken lane marking. R No vehicle is detected in the adjacent lane. R The driven speed is between 50 mph

(80 km/h) and 110 mph (180 km/h).

R Active Lane Change Assist is switched on in the multimedia system. R Active Steering Assist is activated and active.

If no vehicle is detected in the adjacent lane and a lane change is permitted, the lane change begins after the driver has activated the turn sig nal indicator. This is shown to the driver with a green arrow next to the steering wheel symbol. The Lane Change to the Left message, for example, also appears. If Active Lane Change Assist has been activated with the turn signal indicator but a lane change is not immediately possible, a gray arrow appears next to the steering wheel symbol, which remains green. When the lane change assistance starts, the turn signal indicator is automatically activated along with the display in the multifunction display. If a lane change is not possible, the arrow is faded out after a few seconds and a new lane change must be initiated. An immediate lane change is only possible on freeway sections without speed limits. If the system is impaired, Active Lane Change Assist may be canceled. The Lane Change Can-

celed message appears in the multifunction dis play. In addition, a warning tone may sound.

& WARNING Risk of accident when chang ing lane to an occupied adjacent lane

Lane Change Assist cannot always clearly detect if the adjacent lane is free. The lane change might be initiated although the adjacent lane is not free. # Before changing lanes, make sure that

the neighboring lane is free and there is no danger to other road users.

# Monitor the lane change.

& WARNING Risk of accident if Lane Change Assist unexpectedly stops func tioning

If the system limitations for Lane Change Assist have been reached, there is no guar antee that the system will remain active. Lane Change Assist cannot then assist you by applying steering torques.

Problems with Parking Assist PARKTRONIC

Example: vehicles with surround view camera

When rear segments1 or all-round segments 2 light up red and the symbol appears in the multifunction display, Parking Assist PARKTRONIC may have been deactivated due to signal interference. Start the vehicle again and check if Parking Assist PARKTRONIC is working at a different location.

If a warning tone also sounds for approximately two seconds every time the vehicle is started, it may be due to one of the following causes: R The sensors are dirty: clean the sensors

and observe the notes on care of vehicle parts (/ page 340). R Parking Assist PARKTRONIC has been

deactivated due to a malfunction: restart the vehicle. If the problem persists, consult a qualified specialist workshop.

Function of the passive side impact protec tion Passive side impact protection is an additional Parking Assist PARKTRONIC function which warns the driver about obstacles at the side of the vehicle. A warning is issued when obstacles are detected between the front and rear detec tion range. In order for an object on the side to be detected, the sensors in the front and rear bumper must first detect the object while you are driving past it. During the parking procedure or when maneu vering, objects are detected as the vehicle drives past. If you steer in the direction of a detected

obstacle and there is a risk of a lateral collision, a warning is issued and the segments light up in color in the display. The segment color changes depending on the distance to the detected obstacle: R Yellow: approximately 1.0 - 2.0 ft

(30 - 60 cm) R Red: less than approximately 1.0 ft (30 cm)

In order for lateral front or rear segments to be displayed, the vehicle must first travel a distance of at least half of the vehicle length. Once the vehicle has traveled the length of the vehicle, all of the lateral front and rear segments can be dis played.

Active Parking Assist

Function of Active Parking Assist % The availability of this function is dependent

on the country. Active Parking Assist is an electronic parking assistance system that automatically searches for and measures parking spaces on both sides of the vehicle when traveling forwards up to approx. 22 mph (35 km/h).

If all requirements are met, the display appears in the multifunction display. The system then independently locates and measures paral lel and perpendicular parking spaces on both sides of the vehicle. When Active Parking Assist has detected parking spaces, the display appears in the multi function display. The arrows show on which side of the road detected parking spaces are located. They are then shown in the media display. The parking space and, if necessary, the parking direction can be selected as desired. When Active Parking Assist is activated, the turn signal indicators are activated based on the calculated path of your vehicle and the function assists you when parking or leaving a parking space by changing gear, accelerating, braking and steer ing the vehicle. Active Parking Assist is only an aid. It is not a substitute for your attention to the surroundings. The responsibility for safe maneuvering and parking remains with you. Make sure that no persons, animals or objects etc. are in the maneuvering range.

If one of the following actions is carried out, Active Parking Assist is canceled: R Parking Assist PARKTRONIC is deactivated. R You begin steering. R You apply the parking brake. R You engage transmission positionj. R ESP intervenes. R You open the doors or the trunk lid while

driving.

System limits Objects located above or below the detection range of the sensors, e.g. overhanging loads, tail sections or loading ramps of goods vehicles, or the borders of parking spaces, are not detected during measurement of the parking space. These are also then not taken into account when calcu lating the parking procedure. In some circum stances, Active Parking Assist may therefore guide you into the parking space incorrectly.

184 Driving and parking

& WARNING Risk of accident due to objects located above or below the detection range of Active Parking Assist

If there are objects above or below the detection range, the following situations may arise: R Active Parking Assist may steer too early. R The vehicle may not stop in front of these

objects.

This could cause a collision. # In these situations, do not use Active

Parking Assist.

Extreme weather conditions, such as snow or heavy rain, may lead to a parking space being measured inaccurately. Parking spaces that are partially occupied by trailer drawbars might not be identified as such or be measured incorrectly. Only use Active Parking Assist on level, high-grip ground.

Do not use Active Parking Assist in the following situations: R In extreme weather conditions such as ice,

packed snow or in heavy rain. R When transporting a load that protrudes

beyond the vehicle. R If the parking space is on a steep downhill or

uphill gradient. R When snow chains are installed. R Directly after a tire change or when spare

tires are installed. R If the tire pressure is too low or too high. R If the suspension is out of alignment, e.g.

Night View Assist

Function of Night View Assist

With the aid of camera2, Night View Assist helps you to recognize the course of the road or obstacles in the dark. The multifunction display then shows a monochrome image of the sur rounding area in front of the vehicle. Infrared

camera1 helps detect pedestrians and ani mals. Night View Assist is only an aid. The driver is responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. % As infrared light is not visible to the human

eye, Night View Assist can remain activated when there is oncoming traffic. The infrared headlamps switch on in the dark from speeds of approximately 5 mph (10 km/h). This means that, while station ary, you do not have the full visual range and cannot check whether Night View Assist is working.

System limitations Night View Assist cannot display objects directly in front of or directly next to the vehicle. It may be the case that objects are highlighted as well as pedestrians or animals. The system may be impaired or may not function in the following instances: R in poor visibility, e.g. snow, rain, fog or heavy

spray.

Blind Spot Assist and Active Blind Spot Assist

Function of Blind Spot Assist and Active Blind Spot Assist Blind Spot Assist uses two lateral, rear-facing radar sensors to monitor the area up to 130 ft (40 m) behind and 10 ft (3 m) directly next to your vehicle. If a vehicle is detected at speeds above approx imately 8 mph (12 km/h) and this vehicle subse quently enters the monitoring range directly next to your vehicle, the warning lamp in the outside mirror lights up red. If a vehicle is detected close to your vehicle in the lateral monitoring range and you switch on

the turn signal indicator in the corresponding direction, a warning tone sounds once. The red warning lamp in the outside mirror flashes. If the turn signal indicator remains switched on, all other detected vehicles are indicated only by the flashing of the red warning lamp. If you overtake a vehicle quickly, no warning is given.

& WARNING Risk of accident despite Blind Spot Assist

Blind Spot Assist does not react to vehicles approaching and overtaking you at a greatly different speed. Blind Spot Assist cannot warn drivers in this situation. # Always pay careful attention to the traf

fic situation and maintain a safe dis tance at the side of the vehicle.

Observe the notes on driving systems and your responsibility; you may otherwise fail to recog nize dangers (/ page 150).

System limits Blind Spot Assist and Active Blind Spot Assist may be limited in the following situations: R if there is dirt on the sensors or the sensors

are obscured R in poor visibility, e.g. due to fog, heavy rain or

snow R if there are narrow vehicles, e.g. bicycles or

motorbikes R if the road has very wide or narrow lanes R if vehicles are not driving in the middle of

their lane

Warnings may be issued in error when driving close to crash barriers or similar continuous lane borders. Always make sure that there is suffi cient distance to the side for other traffic or obstacles. Warnings may be interrupted when driving along side long vehicles, for example trucks, for a pro longed time. Blind Spot Assist is not operational when reverse gear is engaged.

196 Driving and parking

Function of brake application (Active Blind Spot Assist) If Active Blind Spot Assist detects a risk of a side impact in the monitoring range, a course-cor recting brake application is carried out. This is designed to help you avoid a collision. The course-correcting brake application is availa ble in the speed range between approximately 20 mph (30 km/h) and 125 mph (200 km/h).

& WARNING Risk of accident despite brake application of Active Blind Spot Assist

A course-correcting brake application cannot always prevent a collision. # Always steer, brake or accelerate your

self, especially if Active Blind Spot Assist warns you or makes a course- correcting brake application.

# Always maintain a safe distance at the sides.

If a course-correcting brake application occurs, the red warning lamp flashes in the outside mir ror and a warning tone sounds. In addition, a dis play1 indicating the danger of a side collision appears in the multifunction display. In rare cases, the system may make an inappro priate brake application. This brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate.

System limits Note the system limitations of Active Blind Spot Assist; you may otherwise not recognize the dan gers (/ page 196).

Either a course-correcting brake application appropriate to the driving situation, or none at all, may occur in the following situations: R Vehicles or obstacles, e.g. crash barriers, are

located on both sides of your vehicle. R A vehicle approaches too closely on the side. R You have adopted a sporty driving style with

high cornering speeds. R You brake or accelerate significantly. R A driving safety system intervenes, e.g. ESP

or Active Brake Assist. R ESP is deactivated. R A loss of tire pressure or a faulty tire is

detected.

Active Lane Keeping Assist

Function of Active Lane Keeping Assist Active Lane Keeping Assist monitors the area in front of your vehicle by means of the multifunc tion camera (/ page 150). It serves to protect you against unintentionally leaving your lane. You will be warned by vibration pulses in the steering wheel and guided by a course-correct ing brake application back into your lane. Active Lane Keeping Assist is available in the speed range between 37 mph (60 km/h) and 124 mph (200 km/h). Active Lane Keeping Assist can neither reduce the risk of an accident if you fail to adapt your driving style nor override the laws of physics. It cannot take into account road, weather or traffic conditions. Active Lane Keeping Assist is only an aid. You are responsible for maintaining a safe distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane.

If a lane-correcting brake application occurs, dis play1 appears in the multifunction display. The system does not intervene if you activate the turn signal indicator. If the system detects an obstacle, such as another vehicle in the adjacent lane, it will intervene regardless of the turn sig nal indicator. If you leave the lane without using the turn sig nal indicator but an obstacle is detected in your lane, the system will not intervene. You are warned by vibrations in the steering wheel in the following circumstances: R Active Lane Keeping Assist detects a lane

marking.

R A front wheel drives over this lane marking.

Conditions for a course-correcting brake application (vehicles without Driving Assis tance Package) Lane markings were detected on both sides of the lane. The front wheel drives over a continu ous lane marking. % A brake application may be interrupted at

any time if you steer slightly in the opposite direction.

Conditions for a course-correcting brake application (vehicles with Driving Assistance Package) R A continuous lane marking was detected and

driven over with the front wheel. R A lane marking and an approaching vehicle,

an overtaking vehicle or vehicles driving par allel to your vehicle were detected in the adjacent lane. The front wheel drives over the lane marking.

% A brake application may be interrupted at any time if you steer slightly in the opposite direction.

198 Driving and parking

System limits No lane-correcting brake application occurs in the following situations: R You clearly and actively steer, brake or accel

erate. R If a driving safety system intervenes, such as

ESP, Active Brake Assist or Active Blind Spot Assist. R You have adopted a sporty driving style with

high cornering speeds or high rates of accel eration. R When ESP is deactivated. R If a loss of tire pressure or a faulty tire has

been detected and displayed.

If you deactivate the Active Lane Keeping Assist warning and the lane markings cannot be clearly detected, it is possible that no lane correcting brake application takes place (/ page 200). The system may be impaired or may not function in the following situations: R If there is poor visibility, e.g. due to insuffi

cient illumination of the road, if there are

highly variable shade conditions or in rain, snow, fog or heavy spray. R If there is glare, e.g. from oncoming traffic,

the sun or reflections. R If the windshield in the area of the multifunc

tion camera is dirty, or if the camera is fog ged up, damaged or covered. R If there are no lane markings, or several

unclear lane markings are present for one lane, e.g. around roadworks. R If the lane markings are worn, dark or cov

ered. R If the distance from the vehicle in front is too

short and thus the lane markings cannot be detected. R If the lane markings change quickly, e.g.

lanes branch off, cross one another or merge. R If the road is very narrow and winding. R Vehicles with Driving Assistance Pack

age: if the radar sensors in the rear bumper are dirty or covered in snow and an obstacle

is detected in your lane, no lane-correcting brake application takes place.
